There's a really nice Hawk Littlejohn flute for sale on ebay. It's in the key of G from 1994 and looks to be made from cedar. I can't vouch for the seller, but this is an excellent opportunity to own a piece of history. Hawk was far and away one of the most influential Native American flute makers of the 20th century.
Also, the picture above shows the Cherokee Wrap that Hawk fashioned on some of his flutes. Mac Lopez also does this same style of wrap. He learned it from Hawk.
